The Jung room thermostat RTR 231 is an electronic room temperature controller designed for the control of electrothermal actuators in enclosed spaces. It allows for both heating and cooling and is suitable for use in 230 V AC systems. The installation is done flush-mounted in a device box, enabling seamless integration into the room design. The controller offers manual temperature control, allowing users to set a personalized comfort temperature. Additionally, the device features a frost protection function that activates when a window is opened, helping to regulate room temperature and save energy. The Jung room thermostat is not compatible with smart home systems and does not provide a display or noise level indication, making it a simple and effective solution for temperature regulation.
